Book Description
In vision sensation and perception are rarely equivalent. Most notably, humans perceive the world with three-dimensional depth in a manner consistent with having a single, cyclopean eye centered above the nose even though the inputs to the visual system are a pair of binocular inputs each of which is two-dimensional. In this dissertation we address three aspects of cyclopean perception and how each is influenced by its underlying binocular inputs. In Chapter 1 we study how viewing distance affects retinal disparity and how the visual system is able to maintain a depth percept that is invariant to these changes. In Chapter 2 we examine how binocular disparity and monocular luminance cues are integrated to perceive edges. Finally, in Chapter 3 we consider how monocular images from the left and right eyes are combined to optimize the cyclopean image. Together these studies provide insights into how the visual system interprets retinal inputs and transforms them into a single perception of the world.

Book Description
This is a comprehensive survey of binocular vision, with an emphasis on its role in the perception of a three-dimensional world. The central theme is biological vision. Machine vision and computational models are discussed where they contribute to an understanding of living systems.

Book Description
Volume 2 addresses stereoscopic vision. It starts with the physiology of stereoscopic mechanisms. It then deals with binocular rivalry, binocular summation, and interocular transfer. A review of how images are brought into binocular register is followed by a review of stimulus tokens used to detect disparities. Cyclopean effects, such as cyclopean illusions, cyclopean motion, texture segregation, and binocular direction are reviewed. Factors that influence stereoacuity are discussed. Two chapters describe how stimuli in distinct depth planes produce contrast effects, and affect motion perception and whiteness perception. The Pulfrich stereomotion effect and perception of motion in depth are reviewed. The volume ends with a review of applications of stereoscopy.

Book Description
This study defines cyclopean methodology as the "formation of a percept as some central location in the visual system by using stimuli that could not possible produce that percept at an earlier location," and generalizes both the technique of random-dot stereograms and the concept of the cyclopean retina. Published after a decade of research by the author and other workers in the field of visual perception, this books relates current research in such areas as experimental psychology, neurophysiology, mathematical models, and computer graphics.

Book Description
"Binocular vision" literally means vision with two eyes, and refers to the special attributes of vision with both eyes open, rather than one eye only. Our perception under binocular conditions represents a highly complex co-ordination of motor and sensory processes and is markedly different from and more sophisticated than vision with one eye alone. This book reviews our ability to use both eyes, while also providing basic information on the development of binocular vision and on the clinical disorders that interfere with our depth perception, such as strabismus and amblyopia. This book also describes the development of eye movement control, particularly those that are important for reading. In addition, the authors of this book review the phenomenon of ocular dominance (OD) in the light of the types of test used to identify it; question whether inter-test agreement of OD in an individual might be anticipated, and address some practical implications of OD as demonstrated in healthy eyes and in cases where there is compromised binocular function. Other chapters in this book disclose new methodologies in congenital nystagmus eye movements analysis and evaluate heterophoria as an important element of assessment of binocular vision disorders.

Book Description
"The proposed three volumes are the latest installment in Ian Howard's amazing ongoing project of providing the most comprehensive review available anywhereof all aspects of how humans and animals perceive and navigate the three-dimensional world. The current book set is even more complete in its coverage than the two previous editions have been. With 37 chapters, 1800 illustrations, and 8,000 references, it covers psychophysics, coding, physiology, development of systems and functions, results of deprivation, accommodation, physiology of disparity, binocular fusion and rivalry, binocular correspondence and the horopter, linking binocular images, cyclopean perception, stereo acuity, uses of disparity, stereopsis and perceptual organization, the Pulfrich effect, stereoscopic techniques and applications, distinguishing depth from vergence, perspective, shading, and motion parallax, constancies in visual depth perception, cue integrations, motion in depth, pathology of visual depth perception, animal depth perception, feeling, reaching, and moving, auditory distance perception, electrolocation and the thermal senses, as well as comprehensive coverage of animal navigation that could be a book on its own. Ian Howard's books have become landmarks in the field of vision science, and this current project will definitely maintain the tradition for researchers in space perception, visual neuroscience, ophthalmology, optometry, visual development, animal vision, and computational vision"--

Book Description
Binocular vision, i.e. where both eyes are used together, is a fundamental component of human sight. It also aids hand-eye co-ordination, and the perception of the self within the environment. Clinical anomalies pose a wide range of problems to the sufferer, but normal binocular operation must first be understood before the eye specialist can assess and treat dysfunctions. This is a major new textbook for students of optometry, orthoptics and ophthalmology, and also of psychology. Chapters span such key topics as binocular summation, fusion, the normal horopter, anatomy of the extra-ocular muscles, oculomotor control, binocular integration and depth perception. Fully illustrated throughout, the book includes self-assessment exercises at the end of each chapter, and sample experiments in binocular vision functioning.
